摘　　要：以笔者参与的钱塘江大堤某标准堤塘为例,针对其不同堤段存在的不均匀沉降、裂损以及沉降和回弹变形的某些规律性现象,通过工程特点和探测环境的具体分析,采用探地雷达、瑞雷波法和地震映像法基本查明了其原因,并对该堤段质量现状进行初步分析评价.The project characters and prospecting environment are analysised. The standard dam in the Qiantangjiang River has following characters： different degrees of subsidence and split at different sites, and regular subsidence and spring-back deformation. By means of ground penetrating radar, Rayleigh wave and seismic imaging methods, the reason for subsidence and split has been investrgated, and the quality of the dam section has been analysised.
